Technical Committee (TC) Intelligent Transport Systems (ITS) Activity Report 2020

Chair: Niels Peter Skov Andersen, Anemone Technology

Developing and maintaining standards, specifications and other deliverables to support the implementation of ITS Service provision for transport networks, vehicles and transport users, including interface aspects and multiple modes of transport and interoperability between systems.

Intelligent Transportation Systems (ITS) enable smarter, more coordinated and efficient use of transport networks with the potential to increase safety for travellers and the public, minimize environmental impact and improve traffic management.

In ETSI our ITS Technical Committee (TC ITS) is leading the drive to develop global standards for Co-operative ITS (C-ITS), where vehicles exchange information with other road users and the surrounding infrastructure. Applications include road safety, traffic control, fleet management and location-based services, driver assistance, hazard warnings, support for emergency services – and ultimately the realization of fully autonomous driving.

Our standards relate to the overall communication architecture, management and security aspects of C-ITS. As such they provide support for a wide range of services and applications. These include Cooperative Adaptive Cruise Control; Congestion Control; Cooperative Awareness, Perception and Manoeuvre Coordination; and Decentralized Environmental Notification (DEN) to alert road users. In addition we develop conformance test specifications which are crucial for the commercial deployment of the technology, and are closely involved in radio spectrum requirements for ITS.

In 2020 we continued to develop specifications to support multiple access layers such as LTE-V2X PC5 and ETSI ITS-G5. We also updated security standards to support ongoing establishment by the EC of a Public Key Infrastructure (PKI) for C-ITS deployment.

In C-ITS the exchange of position, motion and other information among road users, pedestrians and roadside infrastructure is critical to road safety and traffic efficiency applications. November saw completion of our suite of Technical Specifications related to the protection of Vulnerable Road Users (VRU) including pedestrians, cyclists, motorcyclists and animals whose movements may be less predictable than other vehicles. Developed with contributions from stakeholders around the world, these new specifications define service interfaces and protocols including the VRU awareness message (VAM) format – a continuous signal transmitted by vulnerable users.

C-V2X is a service using mobile communication technology for direct communication as well as network communication between vehicles, from vehicle to pedestrian and from vehicle to infrastructure. Organized remotely in partnership with the 5GAA, our second C-V2X Plugtests™ event in July tested interoperability between devices to support the deployment of C-ITS in Europe. The event enabled ITS stations and Public Key Infrastructure (PKI) vendors to assess interoperability of their implementations and validate understanding of ETSI’s ITS security standards.

Cooperation continued during the year with our Rail Telecommunications committee (TC RT) on Road ITS and Urban Rail applications in the 5,9 GHz frequency band, with revisions to our Technical Report on extension of the band for safety related ITS.

TC ITS also maintained interaction with bodies including IEEE, ISO, CEN/CENELEC and the EC’s CONNECT, GROW and MOVE initiatives.
